It does it first thing in the morning when it cool out or if its been sitting a long time and its cool/cold out. Also, its only difficult when making turns around a corner, not slight turning like when driving on the road. The difficulty feels like a stutter, not a constant force. I don't hear any noise except the squeak you hear when you turn you wheel all the way to one side or the other. Also, I've changed the power steering fluid as well. Everything else feels find. One, one more thing, and i don't know if this is related or not but i went to get an alignment done and the guy said there was no point b/c there was something wrong and it would just go back to pulling to one side.
